"This invention relates to improvementsin chutes and has particular reference to a chute which "may be erected upon buildings undergoing construction 'or demolition into Whichwaste material may be deposited for accumulation in a pile at "the bottom thereo'f,*or for loading upon a truck or'other conveyance which may be positioned beneath the 'bottom'of the chute. c

The principal feature of the invention is to-construct a chuteof a plurality of separate units arranged oneupon the other and which are ofa length approximating the distance between twoof'the floors of a "building, there being mea'ns forsecuring the units in position softhat they produce a continuousen closedchute for any number of consecutive floors which it is to serve.

Another object isto provide a chute which is constructed of a plurality of separate foldable units in order to facilitate the transporting of the device from place to place .or from one building operation to another. A further object is the provision of a chute constructed of a plurality of units; each unit including a plurality of hingedly connected side walls to enable the same to be folded flat when not in use whereby the units may be easily handled and compactly stacked or stored.

A further object is to provide a chute constructed of a plurality of metal units to reduce the fire hazard present in wooden style chutes and which is sometimes caused by the friction of the materials passing through the chute lVith these and other objects in view, the invention resides in the certain novel construction, combination and arrangement of Figure 2 is a perspective view of one of th 60' chute unitsper se. 7

\ Referring to the drawings by reference charactersfthe letter A clesignates a building of'any number of stories and isprovided with a window opening B ateachflO r thereof, the said window openings being inverticalalinement as is the custom in tall building-strum tllres. improved chute is shown in itsentirety in Figureland is constructed ofa plurality of chute-units il O,'the same' bei'n'g' df equal length approximating the dis't'ance be tween the "floors of; the building structure; The chute unit's-lO are'of identical construe tion with the exception of the lowermost or bottomuni't,but which latter unit only 'difiers from the others in a mannerto b'e presently explainedi 9 a i j "Each ofithe units 1 0 is openthroughout its length and is constructedof opposed side walls 11- -11, a front wall 12,-a' nd abackorj rear wall The side edges of thefr'ont wall 12 and rear Wall 13*are connected to the side edges of-the 'sid'ewall liby hinges 14; whereby the said walls may 'befold'ed' orcollapsedintoa Hat condition when the chute is not in use to enable handling and storing of the units. Figure 3 shows "one ofthe-units in a partially folded condition; but it will be understood that the folded-walls will l-i'e one against the other'soas to becompact.

Therear wall 13 is provided with an opening 15 which 'ezit'endsthe width of the back" wall and which opening is adapted to register with a window opening B when' theunit is'in an erected position. Attaching plates 16 are fixed to-the opposed side walls 1' 1 and-extend beyondtherear wall 13 fora purpose now to beexplained. a When a unit 1 1 is, positioned with respect to one'o'fthe window openings, the wings or attaching plates 16 extend through the win-' dowopenings adjacent the side wall-stheredf and which -"a'=resecured --to anchor r'ods 17,

' be fitted into windows of varying heights, and

by turning the rod relative to the clamping head, the said head may be forced into clamping engagement with the opposed wall of the window opening. After the rods have been secured in position, the wings or attachingpla-tes 16 are secured thereto by fastening elements 20 which in the present instance are shown as bolts which pass through openings 21 provided in the attaching plate, and which register with openings 22 extending through the rod 17, and the said bolt being held secure by nuts 23. It will therefore be seen that whenthe respective chute units are secured in position ,to the rods 17 mounted in the re-i spective window openings, the said sections will be securely anchored in position one upon the other to produce a continuous chute extending from one floor to the next and which extends downward to the ground, the lowermost unit 10- being provided with an outlet 24 in the front wall to permit of the removal of'the waste material from the chute, or to enable a truck to be backed in position soas to receive the waste material as itpasses down the chute. I 1 I V Y 1 1 .As previously stated, the opening'15 in the back wall of each unit registers with oneof the window openings to enable waste material fromthe various floors to be deposited into the chutedirect from a'wheelbarrow'or other carrier and the attaching plates 16 serve to prevent the accidental spilling of the material-between the chute and the building I structure during the deposit of materials'into the chute. 7

- From the foregoing description,'it will be seen that I have provided a'waste m'aterial chute which may be erected for. use upon a building during construction or demolition thereof andafter serving one job, it may be taken down and collapsed andtran'sported to 1 another building operation. It will be ap:

preciated that 'at present it is customary to construct such chute of wood'which isdemolished after serving its purpose on a building operation. The life of a chute such as shown and described is unlimited, and should any of the units become broken or worn, they may be readily replaced by new ones. The units are easy to handle and erect s'o that much time is saved in the erectionof a chute than required for the construction of the sorted to if desired, andI do not limit myself to the precise structural details herein set forth, nor to anything less than the whole of my invention limited only by the appended claim. f

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is: I v v In a structure for removing waste building material from buildings having windows, a

chute comprising a plurality of substantially Q rectangular sections arranged in end to end relatlon and each section having side and lnner and outer walls, the inner wall being provided with an opening registering with one of the wlndows for wastebuildingmaterialpand plates attached rigidly to, said side walls and located at the ends ofsaidopening, and means hingedly oining the side.

walls to said front and rear walls to permit collapsing of the chute 1 section, said plates being provided with means at greatly spaced points by which the plates may besecured rigidly within a window opening to hold the chute in an open position. V I

In testimony whereof I aflixmyrsignature.
